Perspective

Use the Perspective tool to change the orientation of a drawing.

Press [Shift] to select multiple objects.
Drag the corner points in and out to change the shape of the object.
Press [Command] and drag the middle points to change the size and angle of the lines symmetrically.

If you press [Command] when the mouse pointer is outside a selection, it becomes a lasso that you can use to draw free-form selection marks around objects.

To activate this tool:

Select Tools > Drawing Tools > Perspective.
Click the Perspective tool on the Drawing Tools toolbar. If the Perspective tool is visible in the Drawing Tools toolbar, press [1] to activate it.
